Analysis of Enhanced Oil Recovery Technology in Extra-high Water Cut Period in Oilfield

Most onshore oil fields in China are the later stage of development, and water content is more than 90%, which increases difficulty remaining mining. In order to improve production, it necessary develop a variety recovery technologies, increase field space pressure, weaken viscosity, factor. Taking L oilfield as an example, paper briefly expounds characteristics extra-high cut period, on this basis, puts forward technology, grasps development rules, realizes technological innovation. The accumulative production reaches 2.32 million tons, factor by 9%, thus providing reference for related workers.
